  duplex
       
           Used to describe a communications channel
          that can carry signals in both directions, in contrast to a
          simplex channel which only ever carries a signal in one
          direction.
       
          If signals can only flow in one direction at a time the
          communications is "{half-duplex", like a single-lane road with
          traffic lights at each end.  Walkie-talkies with a
          "press-to-talk" button provide half-duplex communications.
       
          If signals can flow in both directions simultaneously the
          communications is "{full-duplex", like a normal two-lane
          road.  Telephones provide full-duplex communications.
       
          The term "duplex" was first used in wireless, telegraph, and
          telephone communications.  Nearly all communications circuits
          used by computers are two-way, so the term is seldom used.
